I suppose I have seen it, though I didn't pay much
attention to it...
The Algorithm within router is such that when it needs to
look up for an error return address, it picks them in order:
Sender: ...
Errors-To: ...
MAIL FROM:<...>
( router/rfc822.c:erraddress() )
This, like Tom Samplonius noted, is according to RFC-822...
(Well, "Errors-To:" I could not find..)
... I too have been under impression that when SMTP-envelope
exists, it has absolute override to any headers in the message.
